Excellent product!

I bought the water kefir grains in November 2021, this is a really good product. I have been able to prepare different water kefir beverages and the grains continue growing after each preparation! Excellent product!

Refreshing kefir drink

Extremely easy to make and seems to taste better with every batch.


My whole family has been loving the tibicos. We mix it with carbonated water to cut it a little, but the flavor is great. I add a fig and half a lemon for minerals, and it turns out really nice.

Easy fizzy drink for beginners

Craving sparkling carbonated all-natural water? Water kefir should be your go-to. Make large batches of fizzies in 3 days (4-5 days in the winter)!

I put a tablespoon of brown sugar with one cup of tap water, and stir to desolve. dump in 1 cup of the rehydrated kefir and two generous slices of lemon or any fruit of your choice (citrus fruits like grapefruit, orange, pomelo works well). I use a 1 gallon jar with temperature strips, ordered here, too. This process takes 1-2 days.

For second ferment (for extra fizz and flavour and colour), get a strainer and strain the now cloudy liquid in smaller jars (a jam jar is fine, too, if you are short on jars), put in new fruits (i put frozen strawberries, blueberries, whatever i can get ahold of in my pantry) and even dump in some fruit juice if you want for extra flavouring. The kefirs are happy when there's sugar, happy happy happy. Close the lid, and remember to burp them every 6 hrs because these little water kefirs are happy active fellas. This process takes 1-2 days.

At this point, your water kefirs should be living in a "hotel" in a fridge. I put them in a little container, water covering the top of the kefir grains and feed it a spoonful of sugar every week in the fridge to let them sleep.

p.s. follow fermentation revolution's instructions to rehydrate the grains when you first get them: hint, put the grains in normal temperature water for like 3 days in room temperature? scoop it up when they're plump!)

What a beautiful discovery!

My small grains of kefir were very easy to rehydrate and gave me liters and liters of tart and sparkling drink! They multiplied well over batches and I was able to share with my friends! I bought a lot of kombucha before, but not anymore! The fruit kefir perfectly fills my sparkling craving, and I can personalize my flavors :) Thanks for the tips!
